Piston.
Piston motsi ne mai juyawa a jikin silinda na injin mota. Tsarin piston ɗin za a iya raba shi zuwa sama, kai da siket. Saman piston shine babban ɓangaren ɗakin ƙonawa, kuma siffarsa tana da alaƙa da siffar ɗakin ƙonawa da aka zaɓa. Injinan mai galibi suna amfani da piston mai faɗi, wanda ke da fa'idar ƙaramin yanki na shaƙar zafi. Saman piston na injin dizal galibi yana da ramuka iri-iri, takamaiman siffarsa, matsayinsa da girmansa dole ne ya kasance tare da samuwar cakuda injin dizal da buƙatun ƙonewa.
Saman piston wani ɓangare ne na ɗakin ƙonawa, don haka galibi ana yin sa da siffofi daban-daban, kuma piston ɗin injin mai yana amfani da saman lebur ko saman mai lanƙwasa, don haka ɗakin ƙonawa ya yi ƙanƙanta, yankin da ke zubar da zafi ƙarami ne, kuma tsarin kera shi mai sauƙi ne. Ana amfani da pistons na kan Convex a cikin injunan mai guda biyu. Saman piston na injunan dizal galibi ana yin su ne da ramuka daban-daban.
Kan piston shine ɓangaren da ke sama da wurin zama na piston, kuma an sanya kan piston da zoben piston don hana zafin jiki mai yawa da iskar gas mai ƙarfi shiga cikin akwati da kuma hana mai shiga ɗakin ƙonewa; Yawancin zafin da saman piston ke sha ana kuma watsa shi zuwa silinda ta kan piston, sannan a tura shi ta hanyar sanyaya.
Ana sarrafa kan piston ɗin da ramukan zobe da dama don ɗora zoben piston, kuma adadin zoben piston ya dogara da buƙatun hatimin, wanda ke da alaƙa da saurin injin da matsin lamba na silinda. Injunan masu saurin gudu suna da ƙananan zobe fiye da injunan masu ƙarancin gudu, kuma injunan mai suna da ƙananan zobe fiye da injunan dizal. Injunan mai na yau da kullun suna amfani da zoben gas guda 2 da zoben mai guda 1; Injin dizal yana da zoben gas guda 3 da zoben mai guda 1; Injin dizal mai ƙarancin gudu yana amfani da zoben gas guda 3 zuwa 4. Domin rage asarar gogayya, ya kamata a rage tsayin ɓangaren bel gwargwadon iko, kuma ya kamata a rage adadin zoben a ƙarƙashin yanayin tabbatar da rufewa.
Duk sassan zoben piston da ke ƙasan ramin ana kiransa da siket ɗin piston. Aikinsa shine jagorantar piston a cikin silinda don yin motsi mai daidaitawa da kuma jure matsin lamba na gefe. Lokacin da injin ke aiki, saboda tasirin matsin lamba na iskar gas a cikin silinda, piston ɗin zai lanƙwasa ya canza siffarsa. Bayan an dumama piston ɗin, adadin faɗaɗawa ya fi na sauran wurare saboda ƙarfe a cikin fil ɗin piston. Bugu da ƙari, piston ɗin zai samar da nakasar fitarwa a ƙarƙashin aikin matsin lamba na gefe. Sakamakon nakasar da ke sama, ɓangaren siket ɗin piston ya zama ellipse a cikin alkiblar dogon axis da ke daidai da fil ɗin piston. Bugu da ƙari, saboda rashin daidaituwar rarraba zafin jiki da nauyi tare da axis na piston, faɗaɗa zafin kowane sashe yana da girma a sama kuma ƙarami ne a ƙasa.
Babban gazawar haɗa piston da dalilansu sune kamar haka:
1. Cire saman saman piston. Cire saman piston yana bayyana a saman piston, tare da raguwar ramuka a cikin ƙananan akwati da kuma narkewar gida a cikin manyan akwati. Babban dalilin cire saman piston yana faruwa ne sakamakon ƙonewa mara kyau, don haka saman yana karɓar zafi da yawa ko kuma yana gudana ƙarƙashin babban kaya bayan zoben piston ya makale ya karye.
2, saman saman fashewar piston. Alkiblar fashewar da ke saman saman piston gabaɗaya tana daidai da axis na ramin fil na piston, wanda galibi ke faruwa ne sakamakon fashewar gajiya da matsin zafi ya haifar. Dalili: aikin injin da ya wuce gona da iri yana haifar da lalacewar piston mai yawa, wanda ke haifar da fashewar gajiya a saman saman piston;
3, lalacewar bangon gefe na ramin zobe na piston. Lokacin da piston ke motsawa sama da ƙasa, zoben piston ya kamata ya zama mai ɗaukar hoto mai motsi tare da nakasar silinda, musamman zafin ramin zobe na farko yana da yawa, kuma "tasirin" iskar gas da yankin mai yana shafar shi, don haka gogayya da girgizar zobe suna faruwa a cikin ramin zobe, suna haifar da lalacewa;
4. Zoben piston coke ne da aka makale a cikin ramin zobe. Coking na zoben piston sakamakon man shafawa ko kuma asarar 'yancin motsi na zobe a cikin tanki, wannan gazawar yana da matukar illa. Manyan dalilai: yawan zafi a injin dizal ko aiki na dogon lokaci, don haka man shafawa, zoben piston, da kuma silinda yana da mummunan lalacewar zafi; Gurɓatar mai yana da tsanani, ingancin man shafawa yana da rauni; Na'urar iska ta crankcase ba ta aiki yadda ya kamata, yana haifar da matsin lamba mai yawa ko rashin isasshen iska a silinda, wanda ke haifar da saurin mai. Saboda haka, ya zama dole a tabbatar da amfani da mai mai inganci don hana injin dizal zafi.
Idan kana son ƙarin bayani, ci gaba da karanta sauran labaran da ke wannan shafin!
Don Allah a kira mu idan kuna buƙatar irin waɗannan kayayyaki.
